### [CallerAPI](https://www.g2.com/products/callerapi/reviews)

CallerAPI is a Caller ID, robocall prevention and telecom spam protection platform that gives carriers, MVNOs, CPaaS and UCaaS providers, Voice AI platforms, SIP/VoIP operators, and mobile security vendors real-time phone intelligence to stop spam, reduce fraud, and increase revenue. Through a single scalable API, a self-hosted spam feed, white-label SDKs, and a SIP firewall, CallerAPI delivers: - Spam score, reputation, and complaint history - Business identity (name, location, industry) across 195 countries - Carrier data, number type, and optional HLR lookup - Live fraud and spam detection covering 30+ countries The spam database updates every 60 seconds with 15 days of rolling history, enabling zero-latency blocking at the switch or network edge. Average API response times are under 300 ms, and the infrastructure is built to handle hundreds of millions of lookups per day. Most customers use CallerAPI in two ways: to cut the cost of answering or processing spam calls, and to resell spam protection and caller intelligence as a branded value-added service that increases ARPU and reduces churn. White-label SDKs (Swift, Java/Kotlin, Flutter, React Native) and an Asterisk module let platforms keep their own brand in front of end users. Self-serve plans start at $25/month, with volume tiers scaling to tens of millions of monthly lookups. The Spam Database Feed, SDKs, and turnkey integrations are licensed directly to match each deployment. CallerAPI is a founder-led company based in Switzerland, with the main operating entity located in the US, focused on practical, high-accuracy telecom protection that sits quietly in the call path and helps operators, platforms, and apps keep networks clean and customers protected.

Phone verification software helps businesses authenticate the phone numbers of customers or potential clients. Phone validation allows businesses to check phone numbers against a database to ensure that the phone number is in use, non-fraudulent, and can be used for business purposes.

Companies often need this software in an industry where phone numbers are commonly used, such as e-commerce, finance, marketing, telecommunications, and online services. These products offer a range of features, including number validation, carrier lookup, number formatting checks, country code validation, blacklist screening, and identification of phone types. Phone verification tools are typically used by sales, IT, customer service, and HR teams.

By employing various checks, organizations can effectively evaluate customer profiles, confirm identities, and thwart fraudulent activities. Phone verification software usually sources information from a CRM or internal database where personal data is stored. It uses automated SMS messages and voice calls to send one-time passwords (OTP) or verification codes to ensure ownership of the phone number.

This often happens when an employee wants to verify their customer has an actual phone number or if they need to collect a phone number for a [CRM platform](https://www.g2.com/categories/crm). This enhances security by ensuring that only legitimate users with access to the associated phone number can answer the phone and be considered customers, thus mitigating risks associated with fraudulent activities like fake accounts or unauthorized access.

Maintaining accurate customer data and facilitating secure communication channels between businesses and clients are imperative functions of this software, contributing to a safer and more trustworthy digital environment.

Phone verification tools are often implemented by the IT department to validate all phone numbers incoming to a company. Other products that help verify customer data include [email verification software](https://www.g2.com/categories/email-verification), which helps check for email usage, and [age verification software](https://www.g2.com/categories/age-verification), which ensures external clients are of an appropriate age for business. If an organization has data privacy authentication concerns, [identity verification software](https://www.g2.com/categories/identity-verification) helps verify in-person or online identities.

To qualify for inclusion in the Phone Verification category, a product must:

- Enable users to accurately verify phone numbers and user identities
- Send one-time passwords or codes via SMS or conduct a voice-based verifying process
- Notify users of fraudulent activity concerning customer phone number information
- Use or integrate with a CRM or internal database for sourcing phone data
